Sounds like a motor from a fan or something running runs about 10 seconds and stops

Do you have the A/C on?

My 2011 just started doing the same thing tonight. I turn the ignition off and and a fan like sound turns on for about 5 seconds then turns off. Never did it before. Turned ignition off with a/c both on and off and did it both ways. Will explore more tomorrow.

Since you have multiple threads with the same question I'll say it again here. It's most likely the vents opening/closing. This happens so your vents aren't open to the outside while the truck is turned off. My 2008 has done it since day 1, it's just loud enough when I turn it on that I don't hear them opening.
